Pricing Details

MiniMaxLaunched 2026-10-19, model ID MiniMax-M3.1-Flash. One flat card with no context tiers: $0.15 input, $0.015 cache read (90% off), $0.60 output. No cache-write rate, batch rate or Priority row published for it (M3 has Priority at 1.5x). Identical to DeepSeek V4.1 Flash's OFF-PEAK card on input and output, but it does not double during DeepSeek's weekday peak windows; cache read is 5x DeepSeek's off-peak $0.003. Same input as Qwen3.8 Flash and $0.13 more on output; Qwen's implicit cache hits bill 20% of input ($0.03), explicit 10% ($0.015) after a 125% creation charge. 1M context per MiniMax's models page; max output not published (OpenRouter reports 524,288). Weights 'will be released later' per MiniMax; Artificial Analysis lists it as proprietary for now; params not disclosed. Ran anonymously as 'Space Bunny' before launch. Artificial Analysis (read 2026-10-22): Intelligence Index 43, $0.22 per index task, 180M output tokens, 92.8 tok/s (MiniMax claims 170+ P50). Same page: DeepSeek V4.1 Flash 1017 scores 45 at $0.26/task but AA prices it at the $0.30/$1.20 PEAK rate, so off-peak it is about $0.13. Claude Haiku 5.5 43 at $0.21, GLM-5.3-Flash 42 at $0.28, GPT-6 Luna (max) 38 at $0.07, MiniMax M3 29 at $0.51. VentureBeat reports an AA-Omniscience hallucination rate of 93%. Vendor-reported: BankerToolBench 76.2, DeepSWE v1.1 73.7, OSWorld V2 61.7, Agents' Last Exam 29.6, CyberGym 82. OpenRouter lists only a :free variant as of 2026-10-22.
